How to use decorators in react server side rendered app?

I have an app(with SSR) running. Recently I tried adding decorator support. I have done the configuration and app runs perfectly fine when it runs in the browser (Because code running in browser is babel-transpiled).

However code(Component containing decorator) breaks when it is rendered on server-side - May be because, the code which is getting executed is not transpiled and node is not able to understand @ symbol.

It it throwing below error

   (node:1932) UnhandledPromiseRejectionWarning: SyntaxError: 
src/components/common/InputBox/InputBox.js: Unexpected token (8:0)

        import './InputBox.scss';
           7 |
        >  8 | @autobind
             | ^
           9 | class InputBox extends Component {
          10 |     constructor(props) {
          11 |         super(props);

How can I fix this?

Thanks

Seems like you haven't set up support for decorators. That means that your code is not transformed, and node (which runs your server script) don't know how to process @foo kind of code. Decorators at 2nd stage (see https://tc39.github.io/proposal-decorators/ ) and not part of the language. If you use babel to transform your code, add corresponding plugin (@babel/plugin-proposal-decorators).
